What insurance do you use for foals?

[emmanash]

and how much do you pay a month for it?
I'm hoping to buy a youngster in the next month or so and am looking at quotes from different insurance companies. I think i'll only need insurance against vets bills because i'm a gold member with the BHS so get public liability with them but will check if it covers more than one horse as I own one already. Had a quote from Petplan but that works out more than it is for my riding mare which surprised me.
Many thanks in advance

I insure my foals with NFU. I have personal liability cover for all my horses as part of my BD membership.
